Summary
👤
SeniorDidier Chételat is a Senior Researcher at Huawei’s Noah’s Ark Lab in Montreal with 11 years of experience advancing AI at the intersection of graph deep learning, combinatorial optimization, and machine reasoning. Previously he led research efforts at Polytechnique Montréal under the Canada Excellence Research Chair in Data Science for Real-Time Decision Making and has academic roots as an assistant professor and long-term research assistant at Cornell. He focuses on bridging theory and practice—developing models and algorithms that tackle structured decision problems and scale to real-world systems. Colleagues describe him as someone who blends rigorous academic training with applied experimentation, often seeking elegant, optimization-driven solutions rather than brute-force learning.
